March 12 is an unusually busy night for live music in New Orleans, especially for a run-of-the-mill Wednesday. Options run the gamut from an alt-rock duo to a left-of-center R&B singer-songwriter to a sax legend to a homegrown blues/hard rock trio.

Broken Bells, Civic Theatre, 8:30 p.m.

Broken Bells boasts an impressive indie-rock pedigree: It consists of James Mercer, the singer/guitarist of the Shins, and Brian Burton, better known as hit-making producer Danger Mouse. As Broken Bells, they recently released their second full-length album of experimental yet melodic pop, “After the Disco.” On tour, the duo is joined by a full band.

“Fun Under the Frescoes,”St. Alphonsus Art & Cultural Center, 6 p.m.

The third season of the concert series to benefit the Irish Channel church-turned-arts center concludes with the McTeggart Irish Dancers and Beth Patterson.

Dave Liebman, The Sandbar at the Cove, 7 p.m.

The spring season of the “Jazz at the Sandbar” concert series on the University of New Orleans campus kicks off with legendary saxophonist Dave Liebman. Admission is free for UNO staff, faculty and students with ID, $5 for the general public.

For the past month, the trombonist has downsized his weekly Wednesday gig at Snug Harbor to a sextet. But this week, he restores the full Uptown Jazz Orchestra.

Star & Dagger, One Eyed Jacks, 10 p.m.

The blues/metal/garage rock ensemble consisting of New Orleans bassist Sean Yseult, vocalist Marcy von Hesseling and New York guitarist Dava She Wolf released its debut full-length album, “Tomorrowland Blues,” in the summer of 2013; it evokes a glammed-up spin on classic Blue Cheer/Black Sabbath crunch. The Cons & Prose, featuring Yseult’s Rock City Morgue bandmate Rik Slave, opens the show.

Cody ChesnuTT, Tipitina’s, 9 p.m.

Over the past dozen years, singer, guitarist and composer Cody ChesnuTT has carved out a name for himself on the neo-soul/contemporary R&B underground with such adventurous recordings as 2002’s “The Headphone Masterpiece.” The Honorable South opens for him at Tipitina’s.
